TIRE-INFLATER.

SPECIFICATION forming part of Letters Patent No. 691,745, dated January28, 1902.

` Application inea July 1e, 1900.-

T0 @ZZ whom it may concern:

Be it known that I, JOSEPH H. CHAMP, a citizen of the United States, anda resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Tire-Inliaters, ofwhich thefollowing is a specification, the principle of the invention bein gherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish itfrom The object of the inventionis to provide an improved tire-iniiater, especial attention having beengiven to same in its fitness for use as connectedwith coin-controlledapparatus.

The nature of the invention consists ofthe means hereinafter described,and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the' invention, such disclosed meansconstituting but one of various mechanical forms in which the principleof the invention may be used.

FigureI, is a vertical transverse section through the casing of themachine, but without section through the inclosed mechanism.

inclosed by the casingand showing the latter in vertical section atright angles to the section of the preceding figure. Fig. III is a View,taken like the immediately-preceding one, of a modiied form of thecasing-inclosed mechanism. Fig. IV is a detail top plan of the handlemechanism connected with the duplicate valve mechanisms and of thecoincontrolling mechanism. Fig. ,V is a front ele- Vation of .saidmembers of the immediatelypreceding ligure, but having that portion ofthe front casing which carries the handle removed. Fig. VI is a detail,partly in vertical section and'partly in vertical side elevation, of oneof the twin valve mechanisms shown in the immediately-preceding gure.Fig. VII is a detail of a portion of the coin-controlling mechanism.Fig. ...VIII is a detail at right angles to the plane in which theimmediately-preceding4 gurey is taken. Fig. IX is a detail view, mainlyin' vertical section, of

struction, its purpose being to exclude the with a door a, wherebyprivileged access may. l

be had to its interior. Two upright cylinders B B are provided, thelarger one, B, being a storage-cylinder of compressed carbonic-acid gasandthe smaller one, B, being a measure-cylinder to permit a givenlimited volume of gas to be subject to draft upon insertion of a certaincoin into the coin-slot. Cylinder B communicates by tube b witlgthepressure-regulator c, having a gage-dial c', subject to conditionsadapted to automatic-x ally cause gas from such storage-cylinder to passunder a predetermined pressure into the tube d. This tube d carries theiiuid to the bottom of the valve-cylinder e, wherein communication withthe tube f, connected with the upper side portion of said cylinder, iscontrolled by a valve having a tendency to be maintained in raisedposition by a spring, such raised position of the valve shutting 0Ecommunication Within the valve-chamber be-v tween said tubes d and f.This valve mechanism controls the induction of the iiuid relatively tothe measure-cylinder and is a duplicate of the valve mechanism,hereinafter referred to, which controls the eduction of the iiuidrelatively to the measure-cylinder, and the interior construction ofeach such Valve mechanism is shown by the single view of Fig.VI. Saidtube f discharges into the lower portion ofthe measure-cylinder B', theupper portion of such measure-.cylinder connecting with one extremity ofa tube g, the opposite extremity of said tube g connecting with thebottom of valve-cylinder h, such cylinder h being of construction andhaving an inclosed upwardly spring-pressed valve such' as shown in Fig.VI, the upper side portion of such cylinder h connecting with tube t,

Awhich latter connects with the vtire-feed noz--v .imi

zle j, projecting vout through the lower por--fV i tion of the frontwall of the casing A.

Each of the twin valve-cylinders cand h has IOO of the latter havingfree sliding movement in bearing-boxes 7a. Said lever, stem, and cam otthe induction mechanism are respectively lettered, as l m 0, While thecorresponding members of the eduction mechanism are respectivelylettered, as Z m o'.

Rock-shaftD has a sleeve E threaded thereon and ad justably clampedthereto by a setscrew 19, such sleeve having rigidly secured thereto aweighted arm q. The rock-shaft is further provided with a rigid arm r,adapted to work freelym within a slot s, formed longitudinally in ahorizontal plate F, located beneath the horizontal slide C. Therock-shaft is adapted to be Operated bya handle G, which is suitablyfitted in and projects outwardly from the central portion of the frontWall of the casing.

A coin-slot H is in the front wall of the cas ing and connects with acoin-chute L, terminating above receptacle t. An additional chute N islocated below the discharge end of plate F, and a cash-box P is located'below the discharge end of such chute.

The slide C has its approximately middle portion provided with atransverse receptacle i, of size adapted to receive a desired coin in avertical plane above said plate F. Said coin-receptacle t has its lowercentral portion formed with an opening -v of size suitable to permit armr to work freely therein when there is no coin in receptacle t.

The construction of the foregoing members is such that when a coin hasentered vreceptacle t it drops onto plate' F and there remains as abarrier against the passage of arm fr through opening o, so that whenhandle Gr is turned to the right arm r engages against the face of thecoin, and the latter then serves as a mechanical member to cause slide Cto be correspondingly moved to the right until the coin has reached avertical plane to the rightrof plate F. The coin then being freed fromsupport falls ofA its own gravity into chute N and is therefrom droppedinto cashboX P.

In Fig. III is shown a modification wherein an upright cylinder B2 isintroduced in fluid connection between the pressure-regulator c andtheinduction-valve cylinder e. The purpose of such cylinder B2 is to permitany cool and condensed carbonio-acid gas to warm and rarefy before beingsubjected to draft for tires. Such expansion-cylinder has its topprovided with fluid connections, such as shown in Fig. IX. Tubesfand gin this instance are shown as each communicating with the top of themeasure-cylinder B'.

The operation of the machine is as follows, assuming certain members inposition such as is shown in Fig. V: The bicyclist removes the cap fromthe nipple of his tire and places his wheel on the tire-feed nozzle j,with the opened nipple fitting in the open end of such nozzle,the mouthof the latter being of size and shape adapted to eeet substantially anairtight joint with such open nipple of a wheeltire. The bicyclist thenslips a suitable coin into slot H, whence the coin passes down chute Linto coin-receptacle t. The bicyclist then turns handle G toward theright, causing arm r to throw slide C toward the right, thereby causingcam o to be disengaged from lever l, so as to permit stem m of theupwardly spring-pressed valve in cylinder e to rise, resulting in saidvalve rising and closing communication between tubes cl and f, andsimultaneously therewith cam o depresses lever Z', which latterdepresses stem m of the upwardly spring-pressed valve in cylinder h,resulting in said valve lowering and opening communication between tubesg and t, and inasmuch as the measure-tank B was under the assumedcondition existing pre viously to the movement of slide C to the rightfilled with gas under pressure such gas in said measure-cylinder passestherefrom, through-said'open communication in cylinder h, out to thetire-feed nozzlej. By reason of the measure-cylinder B having been cutoff by said movement ot' slide C toward therght from communication withtube d it becomes impossible for the bicyclist during the presentcondition of the mechanism to obtain any more gas than had beenpreviously passed from tube d through the induction-cylinder e. Thebicyclist continues hold of the handle Gr, so as to maintain slide C inits said thrown position toward the right until he has satis- Iiedhimself as to the delivery of gas from the tire-feed nozzle. When he isso satisfied, he may let go of handle G, whereupon the weight of arm qwill be sufiioient to overcome the inertia of slide C, and rock-shaft Dwill thereupon be automatically thrown back to the left into theposition shown in Fig. V. Lever Z' will thereupon be released from cam0', and stem m' of the upwardly spring-pressed valve in cylinder h willrise, so that said valve in its corresponding rising movement may cut 0Hcommunication between tubes g and t', and simultaneously therewith cam owill depress lever-Z, which latter will depress stem fm, thereby causingthe upwardly spring-pressed valve in cylinder c to be depressed, so asto open communication between tubes d and f. The eduction means of themeasure-cylinder will thereby be cnt off, while the induction means ofsaid cylinder will thereby be established in open communication, so thatgas under pressure may `pass freely into the measure-cylinder and bethere retained ready for a repetition of the previously-describedoperation.
